Residue: Mathematics

Residue is mathematics you do, not read. Every problem is generated on your device and checked before you see it, and one you have solved is not served to you again. FOUR WAYS TO PLAY • Crucible: modular powers, Diophantine equations, power sums, counting, inequalities, geometry, polynomials, trigonometry and linear algebra, at a tier that follows your recent results. Sprint puts it against the clock, with a countdown on the Lock Screen. • Chromatic Ramsey: colour every edge of a complete graph without making a forbidden shape in one colour. Hints name an edge and the reason for its colour. Two boards cannot be won, and finding out why is the lesson. • Spoof Hunt: a derivation reaches something false. Exactly one step is illegal. Find it. • Daily Conundrum: one problem a day, the same on every device, with a streak to keep. ANSWERS, NOT GUESSES • No multiple choice. Answer on the pad…
